This tool is built for implementation and data migration teams to replace Excel, one-off Python scripts, and expensive CSV importers like FlatFile and OneSchema.

You can visually build logic and validations without code. API/DB connectivity to pull and push data. The tools uses mapping file/config for repeatable data formatting/transformations. AI integrated as well to write the mapping file from plain english.

I'm an implementation consultant and was personally dealing with those tools and driven mad which is why I developed this.

Would be super appreciative of feedback from the HN community!

Happy to chat more or give you access. You can reach me at [nate@dataflowmapper.com]

Hey HN! We built Lunon to make LLM development way less of a headache. Ever wanted to see how different models handle the same prompt without all the setup hassle? That's what we fixed.

Our API lets you compare Claude, GPT, Mistral and others in real-time with just a few lines of code. No more complex infrastructure or managing multiple API connections - we handle all that boring stuff behind the scenes.

Plus, you can cut costs by intelligently routing requests to the right model for each task. Use the powerful (expensive) models only when you really need them.

If you're building with LLMs and tired of the integration headaches, would love to hear feedback!

I found myself collecting a ton of different styles to explore and get inspiration for other photos so I built this to share the collection with others. The site was also completely coded using ChatGPT.

I like to work with my monitor in portrait orientation. The problem is, I'm often sharing my screen or recording Loom videos, and it's exceedingly difficult for others to read my screen or see whats going on.

Are there any solutions here, like sharing a region of my screen only, and dragging windows into it? I can always just share a single window, but when I switch apps I have to share the new window.

How are my fellow portrait-mode people solving this?
